More on the security situation. Brian Ross tracking the latest. We heard from Amy, 40,000 expected to come tonight, more than 40 world leaders. Everyone is on the high state of alert. Russian officials say they are unfazed about security and terror threats and concerns. Confident that their ring of steel as president Putin calls it will protect the games. It's a ring of steel that involves tens of thousands of armed security personnel along with naval ships out in the black sea. There are surveillance blimps overhead to pick up any possible chatter between terrorists and as well, deep in the mountains of sochi overlooking the olympic sites there are anti-missile batteries all there, George, to protect the olympics. President Obama and a lot of other world leaders not going. Something of a rogues gallery. Of despots and dictators. Including the president of Kyrgyzstan. That country's known according to the state department for mistreatment, torture and extortion and bride kidnapping then the president of thajikstan and Kazakhstan known for arbitrary unlawful killings so those will be the honored guests with president Putin That's something. Thanks very much.
